Question

subtract the sum of (x^2-2y^2+xy) and (y^2+z^2+xyz) From the sum of (z^2-2zx-xyz) and (x^2+xy)

If the question is not clear u can look at the pic and answer this with explanation​

Answer 1

Step-by-step explanation:

(z²-2zx-xyz) + (x²+xy) = z²-2zx-xyz+x²+xy

(x²-2y²+xy) + (y²+z²+xyz) = x²-2y²+xy+y²+z²+xyz

(x²-2y²+xy+y²+z²+xyz) - (z²-2zx-xyz+x²+xy)

x²-2y²+xy+y²+z²+xyz-z²+2zx+xyz-x²-xy

= 2zx + 2xyz
